To all whom it may concern:

Be'it known that I, 'Ronnn'r A. Scansonoven, a citizen of the United States, residing' in Philadelphia, Pennsylvania, have invented certain Improvements in Sliding Guides for Doors, of which the following is a specification.

One object of my invention is to construct an improved roller guide for folding doors, especially 'the'vestibule doors of passenger car platforms.

A further-objectof the invention is to use a straight track and to arrange the roller guide so that the doors can be folded together and swung back beyond a right angle to the. guideway, without'jamming'o'r straining the parts and without using atrack ottset at the end. This object I attain by mounting the guide rollers in sliding bearings, so that they will travel on a straight track and'will allow the doors to be folded backof the right-angled line.

In the accompanying drawings :Figure 1', is a side view of the upper .portion of the inclos'ed platform of a passenger 'car,,show

ingthe doors-in the closed position; Fig. 2', is a sectional plan view on the line 2'2, Fig. 1, showing the door in the closed positien in fulllines and in the 0 en position in dotted lines; Fig. 3, isa Sid view, partly in section, showing the upper portion of the guide roller: Fig. 4 is an end view of a door,

showing the rails in section; Fig. 5, is a plan view ofFig- 3, showing the doors in their closed 'osition" F1". 6 1s a Ian-view showing the doors in the/open position; and

Fig. 7. is a perspective view of the roller and its slide.

A is the bodyof the car.

B is the roof of. the vestibule.

B is the head plate directly under the i roof of the vestibule.-

- instance, connected by hinges c. door is nttachcd to the rear post B by C, C are the doors, four in the present The main hinges 1:. The. first and second doors are connected by'outsidc hinges, and the secom'l and third doors by inside hinges, and the third and fourth doors by outside hinges, so thatwhen the doors are open theywvill swing on their hinges to the position shown by dotted lines in Fig. 2.

Directly hack of the head plntoll' are two straight rails (1,1), spaced apart,- and arranged to travel between these rails are the Specification of Letters Patent. Application filed Mal-02x9, ma Serial No. seam.

rollers D. These rollers have flanges d;-

which extend over the rails-b, band are mounted on pins 6 projecting from a slide E, V-shaped in cross section-, as shown in- Fig. 7, and adapted to V-shaped undercut.

ways f on the bracket F having a depend ing plate 1 secured tothe door C. Thesev brackets F are secured 'to the outer ends of the second and fourth doors, so that when the doors are opened the rollers D travel be-- tween rails b, b to the position indicated in Fig. 2. It will be noted in said-figure that while the doors are closed, the slide is retracted, as in Fig. 5, but when the doors are Y opened the slide is projected, as in Fig. 6." The projection of the fourth door is more. than the projection of theslide of the second door, due to the fact that the second 'dooris farther away from therail s. .Thus it. will be seen that the rollers. readily accommodate themselves to the straight track, and the end of the track need not be offset to allowthe doors to swing past the line at right angles to the rails.

In order to limit the movement of the slide, I provide a. pin 1] on the bracket F and this pin travels in a groove e in. the

slide. By this construction the slide cannot to a fixed post; a longitudinal guide fall above the doors; aslidc arranged to move longitudinally on the outer end of the second door and guided by the said rail so that it will travel over the guide rail When then "connected together, the first door being hung ioo doors are moved from the open to the closed position; the slide accommodating itself to the position of the doors when open. 2. The combination of two doors pivot-ally connected together; .the first door being hung to a fixed post; longitudinal guide rails. ,whove the doors; a bracket at the outer upper end of the second door and having a longitudinal slideway therein; with a slide adapt- 1' i doors between which the roller travels when ed to the slideway and having a'roller; said roller being located so as to travel between the fixed rails when the door is moved fromthe open to the closed position; said slide accommodating itself to the position of the doors when closed.

'3. The combination of two doors pivotally connected together; the first door being hung to a fixed post; longitudinal guide. rails above the doors; a bracket secured to the outer, upper end of the second door and having a slideway therein; aislide adapted to the slideway; a.-v pin projecting from the 'slideway; a flanged roller mounted on the pin; a stop on the bracket for limiting the movemenvof the slide in one directi'onfand two fixed longitudinal guide rails above the V the doors are turned on their hinges. r 4. The eomhiimtion of two doors pivotally connected together; the first door being "hung to a fixed post; longitudinal guides; a

roller and a sliding connection betweenthc guides and the second door; said -sliding connection. moving substantially parallel to-the face of the said second door.
